There’s a pattern of overlapping circles in the ground pavement around the medical center – but is there any way to estimate how many circles there are? We investigate a few different methods of figuring it out! Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
The sculpture Undulating X is constructed from metal in the shape of a giant chromosome, a discrete spool of DNA within a cell. But if a chromosome were actually this size, rather than microscopic, how big would the person who it belongs to be? Math can help us figure that out. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, uses the mathematical properties of rectangles to help him measure the width of louvers that are extremely high us.

Here, we observe the scale model of the Beal Rocket and wonder how we can estimate the height of this scale model and thereby estimating the height of the actual rocket using some simple and fun math detective work. We ended up coming very close to the actual height! Supplementary Activity Guides to extend student learning at the Frontiers of Flight Museum for K-12 grade levels are freely available here:...

Estimation, quantity, and scale help us understand aspects of the world around us that we can’t always interact with directly – these tools help us understand large objects and numbers, and ways to represent them. We discuss the questions students at the St. Philip’s School and Community Center posed within this math theme to show just how intuitive this can be! This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, an... CONTINUE READING
The Flying Pancake is a fun name for a unique airplane that is no longer in use. We wonder as to why this aircraft was designed to have a flat wing-like body giving it such a large surface area? We explore this unique design and come to understand how this design met its goals but also came at a cost.

The Command Module of the Apollo VII mission has a truncated cone shape which was essential to its goals of leaving the earth's atmosphere and then safely re-entering the atmosphere to bring its crew back to Earth in 1968. Here, we wonder how the shape of the module was an important aspect of its design and learn about cone shapes, air resistance, and surface area.

We notice that the bottom surface of the Command Module of the Apollo VII space mission looks different from the material making up the rest of the module. We learn that this difference is a critical part of the design of the module that brought home the crew of 3 astronauts in 1968. Further, the heat shield material that was developed for the command module’s bottom surface is now something we use in everyday life – great example of innovation that ends up being used far more widely than an...

We explore how to use slope, the ratio of height to horizontal distance, to better understand how stairs are designed based on international building codes to keep us safe.

Ever look into a pool and think, “Wow – that’s a lot of water!” This thought prompted us to consider exactly how many showers one could take using water in the pool at Camp Whispering Cedars. We started by measuring the surface area and perimeter of the pool before determining volume, using the formula, Volume=(Area)(Height). You’ll be amazed at what we discovered!
